Segmentation fault when using properties in QML

Slash200

Hello,

I'm using properties in my QMLs, which uses items in this QML with parent.property. The properties are set by an JS, because I'm creating instances of this in runtime.
In this example the property mainvalue is set by the JS. This code works well on windows, which is my platform where I develop. On my target platform, raspberry with rasbian, it causes a segmentation fault.

property double mainvalue

        Gauge {
            id: vertgauge
            height: parent.height - 50
            width: parent.width * 0.1
            anchors.bottom: parent.bottom
            anchors.bottomMargin: 10
            anchors.left: parent.left
            anchors.leftMargin: 10
            orientation: Qt.Vertical
            tickmarkStepSize : 0
            minorTickmarkCount: 0
            tickmarkAlignment: Qt.AlignRight
            value: parent.mainvalue
            //maximumValue: parent.maxvalue

            style: GaugeStyle {
                valueBar: Rectangle {
                    implicitWidth: 25
                    color: "#9f9f9f"
                }
            }

        }

how do you know that this assignment causes the crash?! Normally this just causes a runtime error, but no crash.
Unless there is some custom type involved and it's property getter/setter has a bug in the C++ implementation.
